Selank: Research overview, identity, and laboratory handling guide

Tuftsin-derived heptapeptide studied in vitro for peptidase stability and neuroimmune pathway research. ≥99% HPLC. Research use only. This guide covers identity, published research context, procurement checks, and storage — RUO only, no clinical claims.

What Selank is in published research

Selank is a synthetic heptapeptide based on the tuftsin sequence with a Pro-Gly-Pro extension. Research use focuses on peptide stability, peptidase resistance, and neuroimmune pathway markers in laboratory models.

The Pro-Gly-Pro tail is verified in MS identity data and HPLC purity is reported at the lot level. Net peptide content supports accurate preparation of assay stocks.

Store sealed lyophilized vials at -20 °C, protected from light. Reconstitute with bacteriostatic water, aliquot, and freeze working stocks.

CoA covers identity, purity, and net peptide content. Batch records are filed by SKU and lot.

The material class "Tuftsin-derived peptide (research)" helps procurement teams group Selank with related reference peptides during comparative studies.

Sequence and identity

Selank identity on the catalog: Common name: Selank; Sequence: Thr-Lys-Pro-Arg-Pro-Gly-Pro; Length: 7 residues; Molecular formula: C33H57N11O9; Molecular weight: 751.88 g/mol; Appearance: White lyophilized powder; Purity (HPLC): ≥ 99%; Net peptide: Listed on CoA; Solubility: Soluble in bacteriostatic water. Copy these into receiving and LIMS before reconstitution.

Mechanisms studied in published research

Mechanism-focused research on Selank is typically conducted in cell lines or biochemical preparations that express the relevant receptor or binding protein for its class.

Design controls that include scrambled-sequence or orthogonal-receptor negative controls when your protocol evaluates Selank pharmacology in vitro.

Report effect sizes with lot number and CoA reference so results can be reproduced if the same Selank SKU is reordered later.

Avoid extrapolating in vitro binding or signaling readouts to whole-organism outcomes; RUO materials are not qualified for clinical investigation.

Procurement and identity verification

Request the lot-specific CoA for Selank at receipt. Verify SKU, variant size if applicable, and identity mass before the lot enters general storage.

Compare HPLC purity to your internal minimum for the peptide family. File chromatogram excerpts when your QMS requires raw data.

Enter net peptide content from the CoA into inventory before calculating molarity for Selank working stocks.

Attach purchase order, packing list, and CoA in one audit folder per lot.

Storage and reconstitution

Store lyophilized Selank sealed at -20 °C protected from light unless the CoA states otherwise.

Reconstitute with bacteriostatic water or a buffer validated for your assay pH. Aliquot to limit freeze-thaw.

For oxidation-sensitive sequences in Selank, minimize open-vial time at room temperature during weighing.
